Toxoplasmosis is an acute infection with Toxoplasma gondii. It can have serious health risks for pregnant women or people with suppressed immune function.
The acquired immune system's lymphocytes (T cells and B cells) attack antigens like bacteria and viruses, and create antibodies that prevent re-infection.
The immune system has two parts: the acquired system (lymphocytes and antibodies that attack diseases), and the innate system (skin and other barriers).
